HEEL-BURNISHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 268,480, dated December5, 1882.

' Application filed April 24, 1882. (N0 model.)

To all whom it may concern:

Be it known that I, WILLIAM GORDON, of Boston, in the county of Suii'olkand State of Massachusetts, haveinvented certain Improvements inHeel-Bnrnishing Machines, of which the following is a specification.

This inventionconsists, first, in producing a heelburnishiug machinewith atool having a substantially vertical burnishing-face and asubstantially vertical reciprocating movement, so as to enable theoperator to hold the boot or shoe without the use ofajack and presentthe heel to the best advantage to the burnishing-tool.

a The invention consists, secondly, in the provision ot'a rest under thetool adapted to support the heel while it is being acted on by the tool,as I will now proceed to describe.

Of the accompanying drawings, forming a part of this specification,Figure 1 represents a side elevation of a heel-burnishing machineembodying myinvention. Fig. 2 represents a side view of the head of themachine enlarged. Fig. 3 represents a top view of the same. Fig. 4represents a section on line am, Fig. 2.

The same letters of reference indicate the same parts in all thefigures.

In carrying out my invention I provide a suitable standard ort'rame tosupportand mechanism to operate a buruishing-tool, A. Said tool has asubstantially vertical burnishingface, a, and a verticallip, a, at theedge of said face, and is adapted to reciprocate vertically, or nearlyso. This arrangement of the burnishing-face and lip and the direction ofthe movement above described enable the operator to watch theburnishingface of the tool during the operation, so that hecan see thatthe work is being properly performed, and also to hold the bed in avertical plane and press it horizontally againstthe burnishing-faceot'the tool,

so that his own weight can be utilized in exerting the desired pressure.

The means for supporting andreciprocating the'toolmay be variouslymodified without departing from the spirit of my invention. In thepresent instance the tool is mounted on a frame, 0, pivoted at D D tofixed standards E E, and adapted to oscillate vertically. The frame isoscillated by an eccentric, F, on a shaft, G,journa-led in hearings inthe post H,

said eccentric bearing on cross-bars i i of the frame G. The shaft G isprovided with apulley, J, which is belted to a driving-pulley, K. L Lare guides to prevent the lateral movement of the burnishing-tool.

The improved arrangement and direction of movement of thehurnishing-face is especially adaptedfor heel-burnishing in which thework is performed without lateral movement of the heel in a direction atright angles to its tread or bottom surface. Hence no particularditficulty is experienced in keeping the bottom of the heel against thelip of the tool. The same arrangementand direction ot'moveuient wouldnot be'applicable to sole-edgeburnishing machines, because the curvatureot'a sole is such that nearly or quite as much effort is required inkeeping the bottom of the sole in contact with the lip as in keeping theedge ot'the sole in contact with the burnishing-t'ace. Hence insole-edge-burnishing machines employ log areciprocating tool without ajack the tool is always reciprocated horizontally, its burnishingfaceand lip being substantially horizontal, so that the operator can exertat the same time an upw'ard pressure on the burnishing-l'ace and aninward pressure on the lip. While thelastnamed arrangement and movementof the tool is the best that is known for sole-edge burnishing, it isnot suitable for heel-hurnishing for the following reasons: First,thebottom surface of the heel which is pressed against the lip is moreabruptly curved at its margin, so thatit would be easily displaced andcaused to slip oflf the lip by the horizontal movement of the tool and,secondly, the operators weight cannot be utilized in pressing the edgeot' the heel againstthe burnishing-t'ace; third,theburnishing-l'aceisnotvisible to the operator during the operation.

It will be observed that by reciprocating the tool vertically liabilityof the bottom of the heel slipping oft from the lip of the toolhorizontally is mainly avoided, there being no horizontal change in theposition of the lip or tool.

R represents a. fixed rest, which is suitably attached to the standardH, and projects under and in front of the operating-face of the tool A,

so as to form a support for the heel while the latter is being acted onby the tool, and prevent the heel from slipping downwardly from thetool. The rest is preferably a metal arm, and the portion of it on whichthe heel hears is preferably eonvexed and smoothly finished.

It will be seen that the rest enables the operator to exert his wholeforce in pressing the heel against the tool, no effort being required byhim to prevent the heel from slippingdownwardly, as it would naturallyhave a tendency to do ifthe rest were not employed.

I claim 1. In a bnrnishing-machinc, the bnrnishingtool A, theburnishing-face aand lip a of which are in a substantially verticalplane, combined With the tool-carrying frame 0, having the horizontalpivots D D and cross'bars I I, and the operating-eccentric F, arrangedupon a driver-shaft, G, to impart to said frame a vibratory movement ina vertical plane, substansesame tially as shown and described, and forthe purpose specified.

2. In a heel-burnishing machine, the frame supporting thebnrnishing-tool and the devices for reciprocating it vertically, andprovided with a fixed rest, R, extending outward below and beyond thetool, and adapted to afford a bearing beneath for the heel in a linewith the path traveled by the tool and beyond the outer face of thelatter, as specified.

In testimony whereofl have signed my name to this specification, in thepresence of two subscribing witnesses, this 15th day of April, 1882.

WILLlAM GORDON.'
